My invention relates to closures for cans, packages or the like whichare adapted to contain powdered substances. More particularly it relatesto such closures having a plurality of sifter openings and a largeopening for pouring, with means for selectively opening either of thetwo.

The primary object of the invention is to provide a novel closure havinga single slide member for opening and closing either sifter or pouringopenings.

Another object is to provide such a closure which is of very simpleconstruction, which may be easily assembled, in which the handle u orengaging means on the slide is positioned to be readily accessible atall times, and in which the slide is held and guided by means formedfrom the main closure wall.

@ther objects and advantages will become apparent from the followingdescriptionand from the accompanying drawings in which:

"Figure 1 is a plan view showing the top of a can embodying thepreferred form of the invention. y

ig. 2 is a fragmentary sectional view taken along the line 2 2 of Fig.1.

Fig. 3 is a fragmentary sectional view taken along the line 3 3 of Fig.1.

vFig. is a fragmentary sectional view showing an alternativeconstruction.

The exemplary embodiment chosenfor disclosure herein is shown as appliedto a can 5 and comprising generally a main closure wall 6 and a slidemember 7 mounted thereon. The wall 6 is preferably attached permanentlyto the upper edges of the can 5 by means of a seam 8 or other suitablecrimping of the two parts.

The slide member 7 is preferably associated with the wall 6 in such amanner that it may be moved in either of two directions selectively toopen either a pouring opening or sifter openings. For the purpose ofassociating the slide member 7 with the wall 6 a pair of spaced parallelslits 10 are formed in the wall 6, and the metal between the slits isodset downwardly from the plane of the wall.

For a purpose which will hereafter appear an aperture 1l is formed inthe struck down port-ion of the wall 6 in such a position as to leavetwo strips 12 of substantial width, one

7 lies above the two ledges 13 and the two l strips 12 while the endportions thereof pass through the slits 10 and lie below the wall 6.

ln order that the slide 7 may be easily engaged for movement, afinger-piece 14 is provided which, in the form illustrated in Figs. Il 2and 3, comprises a riby in the form of a transverse fold of metal formedfrom the body of the slide 7 centrally thereof and extending upwardlytherefrom. ln this form it is desirable to have all of the openingsclosed when the nger-piece 14 is positioned midway between the slits 10.To this end a pouring opening 15 and a plurality of sifter openings 16are formed in the slide 7 so that when the finger-piece 14 is centrallypositioned the pouring opening 15 will lie above one of the strips 12and be closed thereby while the sifter openings 16' will lie above theother of the strips 12 and will be closed thereby. ln the alternativeform illustrated in Fig. 4: a different form of finger-piece is employedwhich is formed from thel metal which is removed from the slide 7 toform the pouring aperture 15. This is donekby severing the metal only onthe two sides of theaperture 15 and the end nearest the end of theslide, thus leaving a strip of metal which may be formed into a roll orcurl 20 which extends upwardly from the slide 7. The use of this form'of fnge'r-piece necessitates only a slight wall.

change in the proportioning of the elements and results in an addedeconomy since it uses metal which would otherwise be wasted.

To open either the pouring opening 15 or I the sifter holes 16vthe slide7 `1s moved by means of the finger-piece 14 until the desired openinlies over the aperture 11 in the wall 6 and t e other opening lies belowthe wall 6 and is closed thereby. v In constructing the preferredembodiment illustrated in Figs. 1, 2 and 3, so that the` slide 7 may beeasily placed in its operative sition, its length is preferably madeslightl)0 less than twice the distance between the s its 10 thus makinit possible to insert the slide without ben 'ng. When so proportioned,stops 17 are provided ,which extend downward from the wall 6 into thepath of the sli'de7 so that the slide i's stop d when the holes thereinare in position a aperture 11 in the wall 6.

Thealternative embodiment shown in Fig. 4, isalso proportioned so theparts ma be easily assembled and so that the walls o the ve the canserve to perform the function of the stops 17 shown in the preferredform.

It will be apparent from the foregoing description that in the closureprovided a single slide member serves to provide sifter and pouringopenings and that this slide is held in f place b means ormed from themain closure t will also be apparent that the arrangement andproportioning of parts herein shown4 provides a c osure which 1s easilyas-j sembled and which is readily operable due to the accessibility ofthe finger-piece.

I claim as my invention:

1. A receptacle closure comprising a wal having two parallel slitsformed therein and the metal between said slits oiset downward- 1y fromthe plane of said Wall, said wall havl ing a single discharge openingformed in said offset portion, and a, slide member having its oppositeends passing through said slits and aving pouring and sifter openingsformed in spaced relation therein so as to be movable selectively intoregistry with said discharge opening.

2. A receptacle closure comprising a wall having two parallel slitsformed therein and a 'discharge opening formed between said slits, aslide member having its opposite ends extending through said slits andhaving pouring and sifter openings formed in spaced relation thereinadapted to be selectlvely brought into .registry with said dischargeopening by moving said slide in p opposite directions, said slide havinga transverse upwardly extending finger-piece formed thereon near itscenter to provide for moving said slide.
